Cruise of the U.S. Flag-Ship Hartford. – From the Personal Journal of Wm. C. Holton.

May 27th. At daylight this morning it was apparent to all who heard the heavy firing of artillery, and rapid discharges of musketry, that an attack had been made by our forces upon the enemy’s works. The firing continued without intermission during the whole forenoon of this day. During the afternoon, occasionally heavy firing of artillery and musketry, the rebels replying at intervals with two great guns; lower fleet bombarding the rebel earthworks at Port Hudson, mortars, or bombers, as our boys call them, engaged also. A report has been circulated about the decks that during Banks’s attack this morning, a battery of six guns had been captured by us, the enemy drove into their main works, and some two or three of our regiments were inside of their entrenchments.
